Guilty as charged; 6 motors with 8" wheels, and relatively small sprockets (for reduction purposes) breaks #25 chain. 6 motors with 4" wheels, and 1:1 sprockets doesn't, because the stress in the chain is considerably less. (Speaking in general terms, for both cases, with the math and experience to back it up!)

Now, if you want to consider the 8" wheels a bad design choice, that's probably fair enough—but it doesn't necessarily mean that there's anything wrong with the chain installation itself, even if it breaks #25.
